Cut aerated concrete with angle grinder

[LjLindgren]

Hello. I have two arches that I would like to make square. The wall is made of fairly porous blocks (light concrete?). The question is whether it is possible to make the cutout with an angle grinder and use a diamond disc, or if I should get a reciprocating saw with a blade for light concrete?

An old hand saw should also work well. An angle grinder spreads unnecessary dust indoors.

If you're not actively looking for a reason to buy a reciprocating saw, you can buy Baco's lightweight concrete saw. If it's real lightweight concrete or porous bricks, it's quite easy to saw.

I wouldn't use an angle grinder.

Just like previously answered, a handsaw usually works if it's lightweight concrete. The angle grinder produces a hell of a lot of dust. There may possibly be thin rebar in certain places but they can be dealt with using a hacksaw or quickly with the angle grinder.

Thanks for the tips! It turned out that a regular saw from Biltema worked perfectly!

Great. I take it you didn't encounter any reinforcing bars at all, then?

Is there any reason why you have saved the middle pillar?

 

[LjLindgren]

Just one, quite thin and was easy to take with the hacksaw.

Not really, understand that the wall isn't load-bearing but worried if it still serves some kind of stabilizing function. So pure cowardice is the reason it's still there.

It looks like there were a couple of beers to celebrate the successful result too, or is it just the photo (and not you) that is sideways?

Great job, in any case.

Just as previously answered, a handsaw usually works if it is aerated concrete. The angle grinder creates an unbelievable amount of dust. There may potentially be thin rebar in certain places, but they can be taken with a hacksaw or quickly with the angle grinder.

"Grönjävulskt" as an exclamation is something I haven't heard before. Please elaborate!

Nice work anyway.

haha, there actually were! But the picture was taken before the beer was consumed, so the sideways picture has no connection to the intake of pilsnerdyck.

Might as well share a picture of the finished result with

Nice. It's impressive that you managed to achieve that in just a few days. Thumbs up.

Thanks! I had actually promised it would be done by Christmas Eve but missed by a day. I'm a relatively new homeowner and so far I find it quite fun to fix things. It's a nice contrast to my job to do something more concrete and tangible.

Hello! Nice job. Wondering how you attached the lining/moldings?
